用wireshark查看 tcpdump 抓取的mysql交互数据

用tcpdump 抓取 mysql客户端与服务器端的交互

1开启tcpdump

 tcpdump -i eth0 -s 3000 port 3306 -w ~/sql.pcap

先故意输入一个错误的密码

[root@localhost ~]# mysql -h192.168.100.206 -uroot -p

Enter password:

ERROR 1045 (28000): Access denied for user 'root'@'192.168.11.201' (using password: YES)

输入正确的密码进入并进行一系列操作

[root@localhost ~]# mysql -h192.168.100.206 -uroot -p

Enter password:

用wireshark 打开sql.pcap 文件

输入的错误密码

登陆成功

来自服务器端的问候

15 4.952968 192.168.100.206 192.168.11.201 MySQL 148 Server Greeting proto=10 version=5.5.25-log

服务器端的状态

访问

select @@version_comment limit 1 返回 Source distribution

SELECT DATABASE()

USE DataBase 返回数据库名

访问的sql

Return

同样可以在抓取程序访问mysql的数据，可以查看执行了哪些sql语句

也可以不用wireshark 方式如下:

#tcpdump -i any -A -s 3000 port 3306 >~/sql.log
#grep "select * from " ~/sql.log|head

备注：-A 以ASCII格式打印出所有分组，并将链路层的头最小化。向mysql服务端传输的sql语句就是以ASCII码形式进行传输。我们就可以使用-A参数查看传输的具体sql语句。
